Delivers Essential Nutrients

While the IONIC Bloom range already contains the necessary primary nutrients for flowering plants, vigorous growth in hydroponic systems can deplete phosphorus and potassium levels faster than usual. Insufficient levels of these essential nutrients can lead to issues like scorched or curled leaves and purple discolouration. IONIC PK Boost supplies an extra dose of phosphorus and potassium to support the rapid growth of plants in any climate.


Promotes Larger Fruits & Flowers

By providing the core nutrients plants need, IONIC PK Boost enables plants to focus on more than just survival. With an adequate supply of phosphorus and potassium, plants can channel their energy into producing larger, higher-quality fruits and flowers within the same time frame.


Greater pH Control

IONIC products are manufactured with a precise process that ensures pH stability. The macroelements in IONIC liquid nutrients are partially buffered, reducing the likelihood of pH fluctuations. This pH stability helps limit plant stress and simplifies the growing process for growers. There is less need for frequent pH adjustments and fewer side effects on plants such as leaf spotting.


How to Use IONIC PK Boost

  • Shake the bottle before use.
  • Add 1ml of IONIC PK Boost per liter of water to a pre-filled hydroponic tank.
  • Mix the solution thoroughly.
  • Apply IONIC PK Boost every week during the flowering stage.
  • In the final three weeks of the plant's life cycle, increase the application frequency to twice weekly and strengthen the dosage to 2ml per liter.

  • One-part PK booster, making it easy to use.
  • Supplies essential phosphorus and potassium nutrients to plants.
  • Made with mineral salts.
  • Suitable for beginner growers.
